DESCRIPTION OF PREFERRED EMBODIMENTS Referring to the said drawings, the outer frames and sash frames of windows are made up of hollow PVC members 1 having a cross-section as shown in FIGURE 1 which comprises a single flange 1a, or of hollow PVC members 2 having a cross-section as shown in FIGURE 2 which comprises two flanges 2a, and these latter members 2 may also be used for mullions and horizontal cross rails. The flanges 1a and 2a are formed with dovetail grooves for receiving draught excluding'seals later referred to. These members I and 2 are formed on their inner and outer edge faces, that is the faces which are directed inwardly of a built-up frame and those which are directed outwardly towards the surface of an opening in which a frame is fitted with pairs of parallel spaced apart longitudinally extending semicircular grooves or recesses 3 having their mouths directed towards one another and in which can be fitted, as a springy or snap fit, complementary shaped ribs or beaded edges 4 formed in spaced apart parallel relation integrally with interchangeable component parts of windows.

The frame members 1 may be joined together at their mitered corners by means of spigots 5 (FIGURE 3), or alternatively, they may be fused bonded together.

Window systems embracing the sections 1 and/or 2, can be used for (a) fixed light windows; (b) casement windows; (c) fanlights; (d) ventilated windows; (e) pivoted sashes, or (f) vertically or horizontally sliding windows.

The sections 1 and 2 which, as previously stated, are made of PVC may have combined therewith component members also made of PVC and illustrated collectively by FIGURES 4 to 7, the use of which are illustrated by FIGURES 8 0t 18 hereinafter referred to.

These PVC component members comprise (see FIG- URE 4) a rebate-forming member 6 for forming a rebated seal on pivotal sashes only and which is formed with ribs or beaded edges 4 which are complemental to the shape of the recesses 3 in the members 1 and 2, and which are a springy or snap fit in the latter. Item 6a is a draught excluding seal.

Item 7 is a glazing bead for single glazing and item 8 a glazing bead for double glazing, and the flanges of both these beads have ribbed or beaded edge portions 4 which can be engaged in the grooves 3 of the members 1 and 2.

Item 9 is a sill member formed with ribs or heads 4 for engaging grooves 3 of the frame members 1 or 2.

FIGURE 5 illustrates solid PVC components for horizontally slidable windows, as shown in FIGURE 13,

wherein item is a two-part bottom rail formed with seatings 11 for the lower horizontal edges of window panes; 12 is a vertical side and horizontal top frame member having channels 12a formed with grooves 13 fitted with draught excluding strips 13a (FIGURE 13), and 14 is a hard PVC handle formed integral with a portion 15 recessed to fit about the edge of a glass pane 35 and having the inner faces of said recess serated as indicated at 1501 for gripping the vertical edge of the window panes. These handle sections are also formed with recesses 16 for the reception of draught excluding sealing strips 17 which co-operate with oppositely located handle pieces when the windows are closed and the handles are centrally disposed, and in this closed position of the window flanges 14a engage in the channels 12a of the frame members 12 and co-act with draught excluding strips 13a (FIGURE 13).

Item 18 (FIGURE 6) is a sill member for a vertically sliding window, later referred to with reference to FIGURE 17, and this member may be inverted and used as a drip member at the top of a window, this member 18 being formed with beads or ribs 4 for engagement with recesses 3 0f the frame members.

Item 19 is a centre meeting bar for vertically sliding windows and item 20 is used for top and bottom bars of such windows, this item 20 being formed with a soft sealing fin 20a.

Referring next to FIGURE 7, item 21 is a fixed front member for a ventilator later referred to with reference to FIGURE 15; 22 is a movable back member; 23 is a continuous hinge and 24 is a section intended to be cut into short lengths, for example half-inch lengths, to f rm a press clip having a bead or rib 24a for engagement by a complementary channel portion 220 of the movable member 22, the latter being formed with a head or rib 2212 which co-acts with a hinging channel 23a of the hinge member 23. Alternatively, the connection between the movable members 22 and the press clips 24 may be replaced by a magnetic catch.

Constructions of windows embodying the components referred to above will now be described by way of eX- ample.

FIGURE 8 is a horizontal section taken through a fixed window frame and is formed of frame members 1, and single glazing is obtained by the use of the single glazing bead 7 which combines with a flange 1a of the member 1 to form a channel for receiving an edge of a single pane of glass 25.

FIGURE 9 is a view similar to FIGURE 8, but showing how the bead 8 is used instead of the head 7 when double glazing 26 is required, with spacer strips 27 interposed between the panes 26. This figure shows the use of frame members 2 having two flanges 2a to serve as a mullion.

Outer frames, when fitted in wall openings, may comprise a frame made of members 1 only and as shown in FIGURE 10 may be sealed by a mastic composition 28, the frame being fixed in an opening by wall ties 29 having prongs 30 which co-act with the grooves 3 in the members 1. This view illustrates in horizontal crosssection a casement window having a sash frame also comprising frame members 1. The outer frame is fitted with draught sealing strips 6a and the sash is provided with a combined hinge and friction stay 31, the latter forming no part of the present invention.

FIGURE 11 shows in horizontal cross-section the outer frame and the sash frame 33 of a pivoted sash such a shown in vertical section in FIGURE 16 adapted to turn about a horizontal axis through 150. FIGURE 11 illustrates how in industrialised or prefabricated building units the outer frame may be formed of frame members 1 which are reversed so that then flanges 1a are directed towards an opening, and is fitted with a draught sealing strip 611 which co-acts with the edge of a wall opening in which the window is fitted and so eliminates the use of a mastic seal 28 as used in FIGURE 10.

The inner edge of the outer frame 32 and the outer edge of the sash frame 33 are fitted with rebate-forming members 6 (also referred to earlier with reference to and shown in FIGURE 4) which extend only half way around these two frame members respectively and are provided with draught excluding strips 6a, the ends of the members 6 on the sash co-acting with the ends of the members 6 on the outer frame to limit further opening movement when the sash 33 has swung through The members 6 are interlocked with the frames 1 by engaging the beads or ribs 4 in the grooves 3 of said frames.

FIGURE 12 illustrates the application of the invention to a window having vertically sliding sashes 34, the sashes forming no part of the present invention but being fitted in outer frames composed of frame members 1 made in accordance with this invention.

FIGURE 13 is a horizontal section taken through a horizontally sliding window comprising an outer frame 1 made in accordance with this invention and comprising horizontally sliding glass panes 35 fitted on their vertical edges with hard PVC handles 14, as illustrated in FIGURE 5.

FIGURE 14 is a vertical section through a casement window using the frame members 1 and sill 9; FIGURE 15 is a vertical section through a ventilator having the components 21 to 23 of FIGURE 7; FIGURE 16 is a vertical section taken through a pivoted sash which turns about a horizontal axis A and previously referred to with reference to FIGURE 11; FIGURE 17 is a vertical section taken through a window having vertically slidable sashes referred to with reference to FIGURE 12 and shows the sill member 18 used as such, and also used in an inverted position at the top of a window to serve as a drip member, and also shows the members 19 and 20 of FIG- URE 6.

Lastly, FIGURE 18 is a vertical section taken through a horizontally slidable window as referred to with reference to FIGURE 13 and shows the use of the bottom rail 10 with the seatings 11 serving as tracks for the bottom edges of the window panes 35, and also illustrates how the tracks for the upper edges of these panes may be constituted by the channel section member 12 of FIG- URE 5.

In all cases it will be noted that the ribs or beads 4 on the various component parts are provided in pairs, so that these beads yield very slightly towards one another when a component is being fitted to a frame member 1 or 2 and then spring apart so as to snap into the grooves 3. If required, the beads 4 may be so spaced apart as to extend across two sets of grooves and engage in the outermost grooves thereof as shown on the sill member 18 at the bottom of FIGURE 17.

Although the invention is primarily concerned with window constructions it is to be appreciated that it is also applicable to analogous constructions, for example door frames and doors, whether or not provided with glazing, and similar constructions having hinged or sliding or pivoted panels.
